WINPOW CONSTRUCTION.

.Application med August '7.1926. semi No. 127,797.

This invention-v relates to windows-morev to the sashes or to the frame,these being not only inefficient in a good many cases, but unsightly andin the way.

One object of my invention is to dispense with the; necessity forseparatev attachments to attain the end aforementioned through novelconstruction of the window parts themselves. s v

Another object ofmy invention is to offset passage of draft air bytrapping and deflect. ing it at the regions of juncture between theWindow frame and the'sashes.

Still another object is to enable securing of the window sashes againstoperation with assurance of absolute weather-tightness in the event ofextreme cold and high winds.

One wayin which the foregoing as wellas other objects and advantages ofthis invention may be readily secured in practice will be apparent from'the detailed YYdescription hereinafter of the typical embodiment shownin the drawings.

Fig. I is a part horizontal section of my novel window structure; and

Fig. II, a fragmentary view 4illustrating certain arts differentlyadjusted.

The rame or jamb of thewindow, herein comprehensively designated 5, hasat each side (only one being represented) a member 6 conveniently-formed from sheet met-al to -t-he hollow configuration shown toaccommodate up and down movement of the sash balance weights 7, 8.Themember 6 is usually known in the art as the weight box, and, in thepresent instance, will be observed as having an opening 9 at the innerside. This opening 9 is bridged by a part 10 which may be convenientlytermed the sash runner strip, the same having rearward flanges 11, 11engaging grooves 12, 12 formed in the weight boX 6. Supported withcapacity for free rotation in bearing apertures of theY sash runnerstrip 10 are adjusting* screws 1313 that take into the retroverted mar.-ginal edges 14, 14of the opening 8 inthe side of the weight box By thisarrangement, the sides of the window frame 5 'are rendered expansibleand contractable for .al

preferably identical in construction, each` comprising a main framemember 17 which 1s offset as at 18 to provide a recess for 4the edges ofthe window pane 19'together with the weather acking 20, and a erimetricref taining mem er 21'to overlap t e packing on the ln-side of the sash.The member 21may be secured by any convenient removable fastemng means,such, for example, as screws whereof one is depicted at 22. As shown,the marginal portions .23, 23, afforded by the members 17, 17 of therespective sashes 15, 16, extend into guide slots 24, 24 which arecoextensive with integrally-formed tubular pockets or channels 25, 25 ofthe sash runner strip 10. The channels 25, 25', it will be noted, arerounded in cross sectional configuration, and the sash vmargins 23formed with counter-rounded anges 26, 26.

By means of the screws 13e-13 aforementioned, the sash runner stripsl-at opposite i sides of the jamb 5-may b relatively adjusted toestablish the normal relation of the parts shown in Fig. I,-that is tosay-with the margins 23, 23 of the sashes 15, 16 running free in theassociated guide slots 24, 24, whlle the -ends of the ianges 26, 26contact with the walls of the respective tubular channels 25, 25. Underthese conditions, draft air entering through the clearances at the guideslots 24, 24 will be trapped in the channels 25,25, and; by virtue ofthe rounded configuration of the latter and the counter rounding of thesash flanges 26, 26, will be whirl' 1 and deiected for expulsion at theregion of ent as graphically indicated by the arrows in ig. I, andthereby prevented from getting past the sashes 15, 16.

If desired, the sashes 15, 16 may be made absolutely. weather tight inextremely cold and windy weather when there is no necessity for openingthem for ventilation, by

tightening up the adjusting screws 1313.l

as Y

well as with provisions whereby the sashes may be secured againstoperation in absolute weather-tight relation to the window -frame orjamb during periods of extreme cold and wind Vwhen universal ventilationis not essential or desirable.

while i have shown and described my invention in connection with Vafire-proof window wholly of metal, the underlying principles areobviously capable of embodiment.V in windows constructed from othermaterials with attendant advantages analogous t those herein pointedout.

'Having thus described .my invention, I claim:

1. In a window, the combination of sliding sashes, and a jamb aordingtubular channels with longitudinal guide slots for engaging side marginsof the sashes, the channels aforesaid being rounded in cross sectionalconfiguration and the lapped sash margins counter-rounded forcooperation in lwhirling draft air thereby to check and'prevent it fromgetting past the sashes.

2. In a fire proof window, the combination of sliding metallic, sashesand a hollow sheet metal jamb affording tubular channels withlongitudinal guide slots for engaging side anges of the sashes, thechannels aforesaid being rounded in cross section and the sash flangescounter-rounded for cooperation in whirling draft thereby to check andprevent it from getting past the sashes. 3. In a window, the combinationof sashes,

and a jamb with longitudinal guide slotsI for engaging margins of thesashes with a i clearance fit and coextensive tubular channels ofrounded cross section to take counterrounded flanges of the sashes, thesides of the J amb being contractable thereby to effect bindingengagement of the flanges aforesaid with the channel walls andconcurrent displacement of the plane of the sashes to close the guideslots for absolute' Weather-tightness.

4. In fireproof window construction, the combination of metallic sashes,a jamb comprising sheet metal weight boxes open at their inner sides,and sash runner strips, also of sheet metal interitting the jamb openins, said runner strips embodyin integral tu ular channels to take lateralanges along the sliding edges of the sashes, and

vmeans enabling adjustment of the runner strips toward the jamb sidesfor binding contact with the flanges aforesaid and Weather-tightness.

5. In ireproof window construction, the combination of sliding metallicwindow sashes, a jamb comprising sheet metal weight boxes open at theirinner sides, and sash runner strips also of sheet metal interitting thejamb openings, said runner strips einbodying longitudinal guide slotsand coextensivetubular channels of rounded cross section to takecounter-rounded flanges of the sashes, and means enabling adjustment ofthe runner strips toward the jamb sides thereby to effect bindingengagement ofthe flanges aforesaid with the channely Walls, andconcurrent displacement of the plane of the sashes for closure of theguide and slots and absolute weather-tightness.

In testimony v whereof, I have hereunto signed my name at Philadelphia,Pennsylvania, this 4th day of August, 1926.

FRANK C. FERGUSON.
